FLY-TRAP.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed October 13, 1906. Serial No- 338.744-

Il'o mil whom it n-my concern:

Be it known that LINGVART HANSEN, av citizen of United States, residing at Orofino, in the county of Nez Perces, State of Idaho, have invented certain new and useful Improvements in Fly-Traps; and I do hereby declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to that kind of fly-traps that comprise -a glass body orinclosure with an upward and inwardly inclined bodv o )cn at the center the body bein su ported upon legs so that flies feeding below the bottom and starting tofly away will be inclined to go toward the light or lightestarea which is through the opening formed through theraised center of the body, and consequently the flies will be trapped in the glass inclosure.

My improvements consist of means for inducing the flies, whereonce starting up the lower surface of the upwardly inclined hot- .tom and reaching a certain point thereon to immediately lly upward through the said central opening in the bottom, and when once inside, will not be induced to crawl orfly back through the opening by which they entered, as is the case with lly-traps of this class as lwretol'ore produced.

The invention is fully and clearly portrayed in the annexed drawings, forming a part of this specification in view of which the nnprovenn-nts will first be described with respect to their construction and manner of use or operation, and then be pointed out in the subjoincd claim.

()ll be said drawingsl*igurc 1 isa side view of the invention, showing means for suspending it i l nu :lhook or nail. sect ional view of the invcm ion.

Similar numerals ol' nth-met designate similar parts or features, as the case nuiy be, wherever they occur.

in the drawings, 30 dcsignaics the body of the trap which may $01 the most part be made of glass. 'lluinc'losure is approximately ol' hall-oval form with an opening 11 Fig. 2 is a central at its top which is normally closed by a sto ple 12. The bottom 13 of the inclosurc or ody is inclined upward from its outer edge toward its center where it terminates in a neck 14 flared outwardly at upper end 15 providing an openin of wide area, wider than the neck 14. T ie bottom of the body at its outer edge is provided with legs 16 so that when the device is placed upon a board 17, or like means, the flies can crawl under the bottom where treacle or sugar may be placed for them to feed upon, and when they start to fly away they will go upward toward the light and either fly through opening 15 or crawl up on the upwardly inclined sides to 'the opening ,whence they will fly into the inclosure.

Unless the opening in the top is quite (Ea-- pacious to let the light therethrough in good volume manyflies crawl out on the board 17 to the light under the bottom of the trap and are not caught. Again, when the opening 15 is spacious many flies after getting into the trap return through the opening and under the bottom and thus esca e. r

In my improvements make the opening spacious and flared as explained, and coat a zone 18 of the neck" and top of the body with an opaque substance or otherwise render said zone opaque so that the flies crawling u on the lower surface of the bottom and ioac ling the opaque zone will see the greatest light thereabove and fly through the opening, while should they start to return from the receptacle or inside of the trap through the neck, they. will turn away when reaching the dark opaque zone and fly back toward the light in the body of the trap.

It is designed to fill the space 19 at the bottom around the raised center with beer, soapsuds or water for the drowning of the flies caught in the trap, while a bait covered with trcaclc or the like 20 may be suspended from the stopple 12 to attract the flies into the trap.

he board 17 may be provided with screweycs 21 for the attachment of chains 22 to enable the trap to be hung up similar to a bird cage.

The trap may be cleansed by removing the 1 inclosure, an annular section of the neck bestopple 12 and pouring or emptying out the in coated to render it opaque. contents and rinsing it in a way well known. il

W hat is claimed is A fly-trap comprising an inolosure of glass having a bottom upwardly and inwardly inclined from its edges and terminating in aneek having a flared mouth opening into the n testimony whereof, I. allix my signature, in presence of two witnesses.
